So if I swap in an 8.8 from a fox mustang, which i am assuming is steel, is this going to be a problem?

If its the same differential, only steel/iron, then I don't see where the problem is. But that's just common sense talking.

People have been running aluminum driveshafts with 8.8s for years. I don't see why you'd have a problem.

Other that the fact the fox mustang has a solid rear axle, yea steel will work ;)

it has a solid rear axles, but the 8.8 centers are the same for solids and irs' - the thing is, one is aluminum and one is steel, so i would be mixing steel center with the aluminum irs - if it's not an issue, i'll go ahead and do it, just concerned about weight, etc.

i should have been more specific and said that i was referring to the center only.

ANY 8.8 carrier will work in the Mark VIII Aluminum housing.

Allright, sorry about that. If you read the wording of your primary post, you can see why I posted that.

by carrier do you mean center?

I mean the gear carrier/posi or non posi unit.

by carrier do you mean center?



The thing that holds the ring gear, and the axle/halfshafts spline in to. But come to think of it, I have never seen an aluminum carrier. I have seen an aluminum Spool, but never a differential.
